{"schema":"threatline.record/2","record":{"id":"CVE-2026-98413","aliases":[],"summary":"selinux: always fill AVC decision in avc_has_perm_noaudit()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: always fill AVC decision in avc_has_perm_noaudit()\n\navc_has_perm_noaudit() is documented to return a copy of the access\ndecision in @avd, but its early return for an empty requested permission\nset leaves the buffer untouched.  All callers pass an uninitialized\nstack variable and afterwards feed it to avc_audit(), and the inode hook\neven stores it in the per-task decision cache.\n\nFill in a deny-all, audit-all decision, similar to avd_init(), so every\ncaller receives a defined value at no cost on the hot path.","categories":["Operating
